This invention relates to machines for shaping and ornamenting wood curtain poles by means of the application of heat and pressure to the surfaces thereof, the structure illustrated in the accompanying drawings and hereinafter described being intended and adapted for shaping or ornamenting the poles helically throughout the length of the latter.

' The main object of the present invention isto provide simple, durable and efficient machines adapted for the above named purposes. i I. ,In the accompanying drawings, llustrating' the invention in a suitable embodiment thereof: e r p Fig. l is a top plan vlew of a machine of the kind specified embodying the invention.

Fig. 8 is afragmentary detail section on the line 88 of Fig. 2.

Fig. 9 is an inverted detail plan section on the line 9-9 of Fig. 8.

The machine comprises a suitable supporting frame which includes the table plate 1 substantially centrally of which there is an opening or hearing for the lower end of a.

vertical shaft 2 on which the Worm-wheel .3 is splined. The main bearing 4 for the shaft 2 is mounted on the table plate 5 disposed above and parallel with the plate 1.

Suspended from the plate 5 are the bearings 6 and-7 forthe mainshaft 30f the ma-' chine, whichcarries a wonn'meshing with the worm-wheel 3 and a spur-gear '9 meshing with a spur-pinion 10 on the shaft of an electric motor or other power source 11. The said worm is not specifically illustrated as unnecessary.

1929. Serial No. 371,431.

Mounted upon the upper end of the shaft 2 is a bevel gear 12 which meshes with the bevel pinions 13 and 14 of counter shafts 15 and 16, respectively, which extend angularly of each other and substantially diagonally of the plates 1 and 5 in horizontal planes parallel with said plates. The shafts 15 and 16 are journalled in sleeve bearings 17 suitably equipped with bushings and which are supported upon brackets 18 and 19, respectively, of plates 20 and 21 resting upon the plate 5 and having overlapping middle portions pivotally engaged with the shaft 2 to permit adjustmentof said plates arcnately about the axis of said shaft for reasons which will hereinafter fully appear. The plates 20 and 21 will be hereinafter referred to as scissors plates.

On the shaft 15 there is mounted a spur pinion 22 which meshes with the internal spur-gear 23 mounted on a shaft 24 journalled at one end portion in the bearing 25 carried by the bracket 18 and at its other end portion in a bearing 26 carried by the vertically adjustable support 27 of the bracket 28 integral 1 i which meshes with an idle spur-gear 30 on a stud shaft 31 carried by the bracket 19 and meshing with the spur-gear 32 on the shaft 33 which is ournalled at one end in a bearing 34 carried by. the bracket 19 and at its other end in a bearing 35 carried by the adjustable support 36 of the bracket 37 integral with the scissors plate 21.

Mounted upon said plate 5 are the supports 38 and 39 for guide sleeves 40 through which a pole 44 to be subjected to the action of the mechanism is passed, the diameters of said sleeves 40 being such as to accord substantially with that of the pole, the instant mechanism being adapted for the treatment or shaping of normally cylindrical poles only to impart to them the shape of heavy rope.

The shafts 24 and 33 are disposed, respectively below and above the guide sleeves 40 for the pole and an gul arly to the axis of the latter. Said shafts rotate at equal speed in the same direction. i. e. clockwise, and each thereof carries a roller 41 and 42, respectively,

to the pole. In the instant case, the rollers 41 and 42 which, in the instance illustrated, are provided With parallel annular ridges 43 bordered by rounded surface formations, the ridges 43 being adapted to impress helical grooves in the pole 44 and rotate the latter as-the shafts 24 and 33 are rotated and, by reason of the continuity of the helical grooves, also serve to impart longitudinal movement shape the pole 44 by the exercise of pressure only but, obviously, if desired, the said rollers .may be suitably maintained hot by gas jets mpinging thereon to thus burn the grooves into the pole. In instances where other ornaientation or ornamental effect is to be imparted to the pole, the surface formation of the rollers 41 and 42 may be other than the ridges 43 as will be obvious, it being also obvious that the said rollers may include other ornamenting means with the said ridges.

As shown in Figs. 5 to 7, inclusive, the bearings for the shafts 24 and 33 are vertically adjustable to thereby regulate or determine the pressure exerted by the rollers 41 and 42 v onthe pole 44 and'to balance the pressures exerted by said rollers upon diametrically v opposite portionsof said pole.

It will. be notedbyreference-to Fig. 5 that f the bearings 25, 26, and 34, 35 are secured to the uprights of the brackets 18, 19 and 28, 37 by means of set-screws or machine bolts 45, 46, respectively, which pass through vertical slots 47, 48, respectively in said brackets.

Figs. 8 and 9 illustrate the means em- I ployed'to adjust the position of the idle gear 30 to accord with variations in adjustment of the shaft 33. The stud shaft 31' has a threaded shank portion receiving the nut 49 and, at its other end has a head .50 provided with recesses 51 presenting parallel side faces engaging the side walls of a slot 52 in the plate 53 which is mounted on a bracket 54' secured to the bracket 19 and vertically adjustable on the latter, thus permitting said idler to be moved both vertically and horizontally into proper mesh withft'he pinion 29 and gear 32.

Thelarms 20' and 21 carryingthe brackets 18, 19 and28, 37 ordinarily will require only very negligible arcuate adjustment to brin :the ridges of the rollers 41 and 42 into suc proper relative positions as to cooperate to produce the grooves in the pole at any desired pitch. Such arcuate adjustment is permitted by providing arcuate slots 56in the plate 5 through which the shanks of the bolts 57,

for clamping theplates 20 and 21 against movement, project.

The relative arrangement of the shafts 24 'and33,'tlie bearings'therefor and-the rollers thereon is such that planes intersecting the ,iective rollers41 and 42 midway between the pairs of annular ridges thereof, intersect each other in the axis of the vertical shaft 2. The axis of the latter intersects the axis of the guide sleeves 40. This relative arrangement permits the pitch of the helical grooves of the pole 44 to be varied by varying the angle of intersection of the vertical planes of the axes of the shafts 24 and 33 with respect to each other and equally with respectv to the vertical plane of the axis of the sleeves 40. j

Obviously the helical grooves of the pole 44 are in the nature of a multiple thread-of it very long pitch. 7

In practice, it is essential that the bearings for the shafts 24 and 33, respectively, be

1 so adjusted in relative elevation that the horizontal. planes of their axes are equidistant from the axis of the guide sleeves 40 for the pole 44 so that the rollers 41 and'42 will exert equal pressures on diametrically opposite'sides of the said pole.

It will be noted that because o'f longitudin'al movement imparted to the pole, 44 by the rollers 41 and 42, there will'b'e a tendencv of the shafts 24and 33"to move longitudinally in the opposite direction and that thisthrust movement must be preventedin order to maintain the rollers 41 and 42 properly positioned relatively to each other and to the axes of the shaft 2 and sleeves40,respectively. To this end the said shafts 24 and 33 are provided'with collars, 58 and 59, respectively, engaging the end faces of the bushings of bearings 25 and 34.

In operation, after proper adjustment of the shafts and impressing rolls, poles are Y successively fed by handto said rolls through one of the guide sleeves and forced into ini tial engagement with said rolls which thereupon impart both rotary and longitudinal movement to feed'the pole into the other of said. guide sleeves where it remains after passing out of engagement with the said rolls,

the next succeeding pole serving to eject the same.
